Combustion demo

November 16, 2021 aerosol, combustion
In this video we will demonstrate that a cigarette combusts tobacco while our leading heated tobacco product does not, by putting each of them in an enclosed environment filled first with air, then with nitrogen gas. Combustion only occurs when there are three main elements: fuel, heat, and oxygen. When even one element is removed, combustion stops. Most toxicants in cigarette smoke are released through combustion, so by eliminating combustion, we can potentially reduce the level of toxicants in the aerosol compared to cigarette smoke.
